This film is based on a true story. The story tells the gripping story of how Francis (François Leterrier), a male protagonist sentenced to death, successfully escaped from prison a few hours before his execution. In order to escape the Nazi prison, Francis planned a perfect escape plan. To ensure that the plan is foolproof, he not only made full preparations for prison escape, but also contacted the inmates in the next cell several times during the only wash time, trying to find an alliance to implement the plan together. But before he could prepare everything, he was sentenced to immediate execution. In the end, he resolutely embarked on the road to escape with the young prisoner boy. With a minimalist narrative structure, a single closed prison space, and a tight timeline, Robert Bresson won the Best Director Award at the 10th Cannes Film Festival (1957) for this film.
